iPiezoelectric Traffic Sensor ye-AVC (uHlelo lweSithuthi oluzenzekelayo)
Inkcazelo emfutshane:
I-CET8311 inzwa yendlela ehlakaniphile yenzelwe ukufakwa kwesigxina okanye okwethutyana endleleni okanye phantsi kwendlela ukuqokelela idatha yezithuthi. Isakhiwo esiyingqayizivele senzwa sivumela ukuba ifakwe ngokuthe ngqo phantsi kwendlela ngendlela eguquguqukayo kwaye ngoko ihambelana ne-contour yendlela. Isakhiwo esicaba se-sensor sichasene nengxolo yendlela ebangelwa ukugoba kwendlela, imizila ekufutshane, kunye namaza aguqayo asondela kwisithuthi. I-incision encinci kwi-pavement inciphisa umonakalo kwindlela ehamba ngayo, yandisa isantya sofakelo, kwaye inciphisa inani le-grout efunekayo ukufakela.

Ukulungiswa kofakelo
Ukhetho lwecandelo lendlela:
a) Imfuneko kwisixhobo sokukala: Uzinzo lwexesha elide kunye nokuthembeka
b)Imfuneko kwindlela yendlela: Ubungqongqo
Indlela yokufakela
5.1 Ukusika indawo yokubeka:
5.2 Amanyathelo okucoca nawomise
I-1, Ukuqinisekisa ukuba izinto zokubumba zinokudibaniswa kakuhle kunye nomgangatho wendlela emva kokuzaliswa, indawo yofakelo kufuneka ihlanjwe nge-high-pressure cleaner, kwaye umphezulu we-groove kufuneka uhlanjwe ngebrashi yensimbi, kwaye icompressor yomoya/ umpu womoya woxinzelelo oluphezulu okanye i blower isetyenziswa emva kokucoca ukomisa amanzi.
2, Emva kokuba i-debris icociwe, uthuthu oludadayo kwindawo yokwakha kufuneka lucocwe. Ukuba kukho amanzi aqokelelweyo okanye ukufuma okubonakalayo okubonakalayo, sebenzisa i-compressor yomoya (umpu womoya ophezulu) okanye i-blower ukuze uyomise.
3, Emva kokuba ukucoca kugqityiwe, i-tape yokutywina (ububanzi obukhulu kune-50mm) isetyenzisiwe
ukuya kumphezulu wendlela ejikeleze inotshi ukuthintela ungcoliseko kwi-grout.
5.3 Uvavanyo lofakelo lwangaphambili
I-1, i-Capacitance yokuvavanya: Sebenzisa i-digital multi-meter ukulinganisa i-capacitance epheleleyo ye-sensor kunye nekhebula eliqhotyoshelweyo. Ixabiso elilinganisiweyo kufuneka libe phakathi koluhlu oluchazwe yinzwa yobude obuhambelanayo kunye nedatha yedatha yekhebula. Uluhlu lomhloli ludla ngokusetwa kwi-20nF. I-probe ebomvu idibaniswe kwingundoqo yekhebula, kwaye i-black probe ixhunyiwe kwisikhuselo sangaphandle. Qaphela ukuba akufanele ubambe zombini iziphelo zoqhagamshelwano ngexesha elinye.
I-2, ukuchasana novavanyo: Ukulinganisa ukuchasana kuzo zombini iziphelo zenzwa kunye ne-digital multi-meter. Umitha kufuneka usetelwe ku-20MΩ. Ngeli xesha, ukufundwa kwiwotshi kufuneka kudlule i-20MΩ, ngokuqhelekileyo iboniswa ngu "1".
5.4 Lungisa isibiyeli sokuxhoma
5.5 Hlanganisa i-grout
Qaphela: Nceda ufunde imiyalelo ye-grout ngononophelo ngaphambi kokuxuba.
I-1) Vula i-potting grout, ngokuhambelana nesantya sokuzalisa kunye ne-dosage efunekayo, inokuqhutywa ngamanani amancinci kodwa amaxesha ambalwa ukuphepha inkunkuma.
2) Lungiselela ubungakanani obufanelekileyo be-potting grout ngokomlinganiselo ochaziweyo, kwaye uvuselele ngokulinganayo ngehamile yombane (malunga nemizuzu emi-2).
3) Emva kolungiselelo, nceda usebenzise ngaphakathi kwemizuzu engama-30 ukunqanda ukuqina kwibhakethi.
5.6Amanyathelo okuzalisa igrout yokuqala
1) Galela i-grout ngokulinganayo kubude bomsele.
I-2) Xa ugcwalisa, i-port ye-drainage ingenziwa ngesandla ukuze iququzelele ukulawulwa kwesantya kunye nolwalathiso ngexesha lokuthulula. Ukugcina ixesha kunye namandla omzimba, inokugalelwa ngezikhongozeli zomthamo omncinci, olungele abantu abaninzi ukuba basebenze ngaxeshanye.
3) Ukuzaliswa kokuqala kufuneka kube neendawo zokubeka ezigcweleyo, kwaye wenze umphezulu wegrout ube phezulu kancinane kunepavumente.
4) Gcina ixesha kangangoko kunokwenzeka, ngaphandle koko i-grout iya kuqinisa (le mveliso inexesha eliqhelekileyo lokunyanga le-1 ukuya kwiiyure ze-2).
5.7 Amanyathelo okuzalisa igrout yesibini
Emva kokuba i-grouting yokuqala iphilisiwe, jonga umphezulu we-grout. Ukuba ubuso buphantsi kunomgangatho wendlela okanye umphezulu ubolile, xuba kwakhona i-grout (jonga inyathelo 5.5) kwaye wenze ukuzaliswa kwesibini.
Ukuzaliswa kwesibini kufuneka kuqinisekise ukuba ubuso be-grout buncinci ngaphezu kwendlela.
5.8Ukusila phezu komhlaba
Emva kokufakela inyathelo le-5.7 ligqityiwe isiqingatha seyure, kwaye i-grout iqala ukuqina, ikrazule iiteyipu kumacala eendawo zokubeka.
Emva kokufakela inyathelo 5.7 ligqityiwe iyure eli-1, kwaye i-grout iqiniswe ngokupheleleyo, igaye
igrout nge-engile grinder ukuyenza igungxulwe nomphezulu wendlela.
5.9 Ukucocwa kwendawo kunye novavanyo lwasemva kokufakwa
1) Coca iintsalela zegrout kunye nolunye ubutyobo.
2) Uvavanyo emva kofakelo:
(1) Uvavanyo lwamandla: sebenzisa i-digital meter meter ukulinganisa i-capacitance epheleleyo ye-sensor kunye nekhebula eliqhotyoshelweyo. Ixabiso elilinganisiweyo kufuneka libe phakathi koluhlu oluchazwe yinzwa yobude obuhambelanayo kunye nedatha yedatha yekhebula. Uluhlu lomhloli ludla ngokusetwa kwi-20nF. I-probe ebomvu idibaniswe kwingundoqo yekhebula, kwaye i-black probe ixhunyiwe kwisikhuselo sangaphandle. Qaphela ukuba ungabambi iziphelo zoqhagamshelwano ezimbini ngexesha elinye.
(2) Ukumelana novavanyo: sebenzisa i-digital meter multiple ukulinganisa ukuxhathisa kwenzwa. Umitha kufuneka usetelwe ku-20MΩ. Ngeli xesha, ukufundwa kwiwotshi kufuneka kudlule i-20MΩ, ngokuqhelekileyo iboniswa ngu "1".
(3) Uvavanyo lwangaphambili lomthwalo: emva kokuba indawo yokufakela icociwe, qhagamshela i-sensor output kwi-oscilloscope. Ukusetwa okuqhelekileyo kwe-oscilloscope yile: Voltage 200mV/div, Ixesha 50ms/div. Ngophawu oluhle, i-voltage ye-trigger isetelwe malunga ne-50mV. Imodeli yamaza yelori kunye nemoto iqokelelwa njengovavanyo lwamaza ovavanyo lwangaphambi komthwalo, emva koko ifom yovavanyo igcinwe kwaye ikhutshelwe ukuprintwa, kwaye igcinwe ngokusisigxina. Ukukhutshwa kwenzwa kuxhomekeke kwindlela yokunyuka, ubude benzwa, ubude bekhebula kunye nezinto zokubumba ezisetyenzisiweyo. Ukuba uvavanyo lokulayisha kwangaphambili luqhelekile, ukufakela kugqityiwe.
I-3) Ukukhutshwa kwe-Traffic: amanqaku: I-Traffic inokukhululwa kuphela xa i-potting material iphiliswe ngokupheleleyo (malunga ne-2-3 iiyure emva kokuzaliswa kokugqibela). Ukuba i-traffic ikhutshwe xa i-potting material ingapheliswanga ngokupheleleyo, iya kulimaza ukufakela kwaye ibangele ukuba inzwa ingaphumeleli kwangaphambi kwexesha.
